What are the tools involved in building surveying?
The most commonly used instruments are the level, theodolite, the total station
Level (Level: Level) is the establishment of horizontal line of sight to determine the ground between the two points of the instrument. The principle is to measure the height difference between ground points according to the principle of leveling. The main components are telescopes, pipe level (or compensator), vertical axis, base, foot screw. According to the structure is divided into micro-tilt level, automatic Anping level, laser level and digital level (also known as electronic level). Accuracy is divided into precision level and general level.
Theodolite, measuring the horizontal and vertical angle of the instrument; is based on the principle of angle design. At present the most commonly used optical theodolite
3. Total station, that is, all-station electronic rangefinder (Electronic Total Station), is a set of light, machine, electricity as one of the high-tech measuring instruments, is set horizontal angle, vertical angle, distance (slope, Horizontal distance), high difference measurement function in one of the mapping instrument system.
